1 Claim.

The present invention relates to a terminal and more particularly to aterminal especially adapted to be removably secured to the post of abattery.

One of the objects of the present invention is 5 to provide a terminalof this character which is so constructed that it may be easily insertedon and removed from the battery post.

A still further important object'of the invention is to provide aterminal of this character 10' which, while being easily removed, is soconstructed that it forms a positive and secure electrical connection onthe binding post of the battery. In the accompanying drawing, whereinfor the 16 purpose of illustration there is shown a preferred embodimentof the invention and in which like numerals designate correspondingparts throughout the same,

Figure 1 is a front elevationalview of a portion 20 of a battery showingthe terminal in position on the battery post,

Figure 2 is a top plan view thereof,

Figure 3 is a longitudinal sectional view of Figure 1 taken on line 3-4thereof,

25 Figure 4 is a perspective view of the terminal,

and

clamping members of the terminal.

In the accompanying drawing, wherein for the purpose of illustrationthere is shown a preferred embodiment of the invention, the referencenumeral 6 generally designates a battery which may be of anyconstruction or size and which is provided with the usual taperedbinding post 6; To 35 this binding post in the usual manner there isadapted to be secured an electrical terminal which forms the subjectmatter of the presentv to pressure contact the outer peripheries of the50 post 8 and securely hold or maintain the terminal in electricalcontacting positionthereon. Each of the clamps i0 and I2 are providedwith transversely extending bores therein which receive the nightportions of a rectangular shaped connect- 55 ing link 20'. Thus, it will'beobserved that the Figure is a perspective view of one of the clampsIll and I2 are pivotally connected by means of the rectangular shapedconnecting link 20 to the end that upon relative movement of theclamping members l0 and I2 the space between the inner surfaces of theclamping ribs I8 may be 5 varied depending upon the shape and size ofthe binding post.

The clamping member i2 is provided with an outward integral tubularextension 22 which rereives, as shown, the conduit 26 electricallyconnecting the clamp l2 to the conduit. Projecting from the other end ofthe clamp l2 on the upper side of the clamp toward the clamp I0 is anextension 24 which is provided with a-screw threaded aperture thereinadapted to receive a screw threaded plug26; It will be observed that theposition of the plug 26 is substantially central of the space betweenthe opposite] disposed inner surfaces of the clamps l0 and 2 to the end,as clearly illustrated in Figure 1, that the inner free end of the plug26 is adapted to contact the upper end of the post 8.

Thus, as shown in Figure 1, the inner surface of'the clamp I0 isdisposed on one side of the post 8 and the inner surface of the clamp l2on 25 .the other side thereof, whereupon the clamps are forceddownwardly until the ridges l8 pressure .contact the outer periphery ofthe post and upon a subsequent turning of the plug 26 and the contactingof the same against the upper sur- 60 face of the post 8 the clamp isfirmly secured in 1 electrical contacting engagement on the post 8. Whenit is desired to remove the terminal from thepost 8 it is only necessaryto raise. or urge one of the clamps upwardly, thereby increasing, byvirtue of the link connection, the space between, the ridges of theclamp enabling the terminal to be easily removed from the post.

' While there is shown for the purpose of illustration a preferredembodiment of the invention 40 it is to be understood that it is capableof various changes "and modifications without departing from the spiritand scope thereof, and it is intended, therefore, that only suchlimitations shall be imposed thereon as are indicated in the prior art.I

What is claimed is:

A battery terminal of the class described comprising a pair of clampingmembers, the inner oppositely disposed surfaces of said clamping 0members being provided with an outwardly projecting ridge thereon, eachof said clamping members having, atransversely extending bore therein, asubstantially rectangular shaped link having the bight portions thereofextending through 5 Jaw said bores and pivotally connecting saidclamping members, means for connecting an electrical conduit to one ofsaid clamping members, one of said clamping members being provided witha lateral extension extending toward the other clamping member and beingprovided with a screw thread-
